Interesting, I'll check out the fans. Wouldn't hurt since the noctua does ruin the asthetics.

Is koolance a good brand for fittings or should I go with another brand?

Customer service from Frozen CPU, seemed rude.

i don't want to come off rude but i wouldn't blame them mate
the customer service is more for direct sales/specification questions, not opinions on how to style your case, you're best bet is to ask on here for help on how to achieve a style/look

xspc make good cheap compression fittings from what ive read. i use barbs, simple, cheap and effective.http://www.performance-pcs.com/catalog/index.php has better prices in most cases. youre best to find other aussies(youre down there arent you?) and ask where they order from.
